What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To construct a nomogram risk prediction model for osteoporotic vertebral compression fracture (OVCF) in postmenopausal osteoporosis (POP). A retrospective study was conducted on 326 POP patients from July 2023 to November 2024. The patients were randomly included into a training cohort of 228 cases and a validation cohort of 98 cases based on a 7:3 ratio; The training queue was assigned into a fracture group of 82 cases and a non fracture group of 146 cases. Risk factors were screened based on multiple logistic regression analysis. R software was used to construct nomogram prediction models. ROC curve, calibration curve, and clinical decision curve were performed to evaluate model discrimination, calibration, and practicality. For the non fracture group, the fracture group showed manifest increases in age, physical exercise time < 1 h/d, gastrointestinal diseases, uric acid, and type I collagen carboxy terminal peptide (β-CTX), and manifest decreases in bone mineral density (BMD) (T value), hemoglobin (Hb), and 5-hydroxyvitamin D [25-(OH)D] (P < 0.05). Increase in age, decrease in BMD (T value), physical exercise time < 1 h/d, presence of gastrointestinal diseases, increase in uric acid, increase in β-CTX, and decrease in 25-(OH)D were independent risk factors for OVCF in POP (P < 0.05). The calibration curves of the training queue and validation queue indicated a high degree of agreement between the predicted results of the model and the actual results, Hosmer-Lemeshow χ
